A collar m and deflector m are connected with sleeves m adapted to slide on the supply-pipe d and on a rod or pipe m and to be clamped to place by means of set-screws m. The collar m carries the globe n and a hinged cap 0, which normally serve to cover the burner. When the cap 0 is opened, the collar, globe, and deflector may be pushed up in order to permit of the lighting or adjustment of the burner. The deflector 'm is provided with the usual vent and wind-cap and with an opening for the accommodation of the lower ends of the pipes g and h and serves to concentrate heat upon the vaporizer f.

The mode of operation of apparatus embodying features of my invention may be described in connection with the accompanying drawings as follows: The wick g by its capillary action supplies liquid hydrocarbon by way of the pipe, passage, or conduit 9 to the vaporizer in proper limited quantities. The vaporizer, by reason of heat imparted to it from the burner, vaporizes or volatilizes the liquid hydrocarbon so supplied to it, and this vapor passes by way of the pipe, passage, or conduit h into the interior of the fount or reservoir and above the contents thereof, and thus serves to force the liquid contents to the burner a by way of the pipe d under that pressure or forced feed which is best adapted for causing the burner to volatilize fluid fueland burn it in combination with air in such manner that the best illuminating efiect is produced from the mantle or incandescent 6.

It will be obvious to those skilledin the art to which my invention appertains that modiiications may be made in details without departing from the spirit thereof. Hence I do not limit myself to the precise construction and arrangement of parts hereinabove set forth and illustrated in the accompanying drawings; but,

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The combination with a pressure apparatus comprising a closed vaporizer having inlet and outlet pipes communicating with a ing from the reservoir or fount and provided with a hydrocarbon-burner, substantially as described.

2. The combination with a pressure apparatus comprising a closed vaporizer having in let and out-let pipes communicating with. a fount or reservoir, of a separate pipe leading from the fount 'or reservoir and provided with a hydrocarbon-burner, substantially as described.

3. In combination, a reservoir having a tube, a burner and burner-supply pipe com municating with said reservoir, nested pipes accommodated bysaid tube and communicating at their upper ends with the interior of the reservoir and closed at their lower ends to form a closed vaporizer exposed to the heat of the burner, and a wick in one of said pipes, substantially as described.

4. In combination a reservoir and its burnerpipe and hydrocarbon-burner, nested pipes whereof one contains a wick and whereof both communicate with the interior of the reservoir, a cap closing the lower ends of said pipes both communicate with the interior of the CHARLES E.
